net/mlx5e: Report zero bandwidth for non-ETS traffic classes

Browse source

[ Upstream commit ffb1873b2d ]

The IEEE 802.1Qaz standard defines that bandwidth allocation percentages
only apply to Enhanced Transmission Selection (ETS) traffic classes.
For STRICT and VENDOR transmission selection algorithms, bandwidth
percentage values are not applicable.

Currently for non-ETS 100 bandwidth is being reported for all traffic
classes in the get operation due to hardware limitation, regardless of
their TSA type.

Fix this by reporting 0 for non-ETS traffic classes.
